I have the American Wire harness and my MSD box mounted in the engine compartment, with its wires routing to the distributor and to the coil.
My question is how do the harness wires tie in. My diagram shows the wires that tie in to the sylenoid for a GM. Please Help!!!! The only driving I'm doing is to drinking.

i haven't put mine in yet, but I bought the adaptor for a mustang. Its a plug and play on a stang, and my thinknig is that it should wire in much easier. I think it was about $25 out of the summit catalog.

I think I bought an adapter also from Mike Forte. Plugged right in and it was cheap.

Assuming you are carbed, if you already have it wired to the distributor and the coil, you will only need to connect the large red wire to a constant voltage source. I'm also using the AAW harness, and connected the small red MSD wire to the AAW wire from the ignition key that is supposed to go to the coil. (can't remember the color). MSD shows the large red wire connected to the solenoid, that will also work in your application. If you are EFI, buy the MSD connector that will connect the MSD box to the distributor. John

Heavy red wire to the battery (usually tapped off of the solenoid battery post). Heavy black wire to ground. Small red wire to ignition coil wire from fuse box. White wire insulated and stowed or used to disable the system by connection to a hidden spst toggle switch with the other side to ground. Orange (+) and black (-) wires to coil. Plug in distributor. Start car!
